Definitions
- the invention relates to a speed-adaptive vibration damper and a torsional vibration damper with this with a rotating about a rotation axis disc part and a plurality of this arranged over the circumference along a forced along an epicycloid first pendulum track first swing angle to a predetermined first pendulum order oscillating absorber masses.
- Speed-adaptive vibration absorbers are used, for example, as structural designs in motor vehicles in the form of centrifugal force pendulums for calming a torsionally vibrating drive train.
- centrifugal pendulums are known, for example, from the documents DE 10 201 1 086 532 A1, DE 10 2010 054 302 A1, DE 10 2010 014 674 A1, WO 2010/127663 A1, WO 201 1/1 41010 A1, in conjunction with other drive train components and in particular combined with other vibration isolation devices such as split flywheels, torsional vibration dampers and the like with non-speed adaptive damping.
- the speed-adaptive Tilgerfrequenz the vibration absorber is obtained by appropriate interpretation of its pendulum order on a main order of an excitation source, such as an internal combustion engine with a substantially dependent on the number of cylinders vibration order.
- the period of a pendulum oscillation of the absorber masses of the speed-adaptive vibration absorber and thus a current vibration order of the speed-adaptive vibration absorber are dependent on a swing angle of the absorber masses.
- the current oscillation order substantially corresponds to the intended coordination order.
- the deviation of the current oscillation order from the tuning order increases. This leads to a deteriorated insulation effect.
- the object of the invention is therefore to propose a speed-adaptive vibration damper and a torsional vibration damper with this, which is effective over the entire operating range of a drive train and avoids attacks of the absorber masses of the speed-adaptive vibration damper or at least makes it unlikely.
- the absorber masses are at a first oscillation angle exceeding the first oscillation angles compared to the first pendulum order changed second pendulum order enforcing second pendulum led.
- the second pendulum order is smaller than the first pendulum order.
- the first pendulum order is matched to the corresponding excitation order of the internal combustion engine, so that internal combustion engines in the form of four-stroke engines with two, three or more cylinders can be vibration isolated. Since in such internal combustion engines when using torsional vibration dampers in conjunction with a speed-adaptive vibration absorber the drive train forms lie in the operating range of the rotational speeds of the internal combustion engine, by means of a combination of a torsional vibration damper such as torsional vibration damper in a clutch disc by increasing the swing angle of the absorber masses without impact Vibration isolation can be achieved even below the intrinsic shape of the drive train.
- a torsional vibration damper such as torsional vibration damper in a clutch disc
- the pendulum vibration of the absorber masses can here in the sense of a filament pendulum, in which an absorber mass oscillates with the given pendulum length to a single pendulum point, or in the sense of a trapezoidal pendulum, in which a damping mass oscillates with the predetermined pendulum length about two spaced in the circumferential direction of the disc part pendulum points be.
- the first swing angle with an epicycloidal pendulum track of a given pendulum order can be provided depending on the existing space between ⁇ 30 ° to ⁇ 60 °, to which the second swing angle is followed. This can for example be limited to ⁇ 90 °.
- the proposed speed-adaptive vibration absorber can be used in a preferred manner in combination with a conventional torsional vibration damper without additional primary and secondary flywheel, so that a cost-effective and space-optimized solution can be proposed.
- a corresponding torsional vibration damper preferably contains the proposed speed-adaptive vibration absorber in the form of a centrifugal pendulum.
- the proposed torsional vibration damper may be formed with the centrifugal pendulum in a clutch disc of a friction clutch.
- a friction clutch may be provided with the centrifugal pendulum, wherein the torsional vibration damper may be provided on the clutch disc of the friction clutch.

- a crankshaft not shown
- the flywheel 10 With the moment of inertia J- ⁇ .
- the torsional vibration damper 8 is arranged with the spring device 7 and the friction device 6.
- the torsional vibration damper 8 can be represented as a split flywheel or as a conventional torsional vibration damper arranged, for example, on a clutch disk or in a hydrodynamic torque converter.
- the torsional vibration damper 8 is designed with respect to its effect for damping torsional vibrations of the internal combustion engine substantially independent of their speed, wherein by means of spring means 7, for example in the form of bow springs, the friction means dependent on centrifugal force and thus speed is variable.
- the second mass 9 is associated with the speed-adaptive vibration damper 1.
- This contains the disc part 2 and two or more absorber masses 3 received opposite thereto in the direction of rotation effectively arranged pendulum tracks.
- the rest of the drive train 4, such as gear, differential and wheels, and vehicle body 5 are schematically by means of mutually elastically connected mass moments of inertia J 3 , J 4 shown.
- the drive train is characterized by a system-related eigenform.
- the absorber masses 3 oscillate with respect to the disk part 2 at a frequency which depends on the rotational speed of the internal combustion engine and thereby cancel out a vibration order when designing the pendulum order, preferably the main vibration order of the internal combustion engine.
- the speed-dependent occurring torsional vibrations according to speed-dependent.
- the pendulum tracks of the absorber masses are formed epicycloid. Due to the cramped space of the speed-adaptive vibration absorber 1, the oscillation angle whose absorber masses 3 are limited, so that they tend at high excitations to strike the track boundaries of the pendulum. To avoid this or at least to limit a high degree, the pendulum tracks are formed in two parts relative to a central position. While at small and medium oscillation angles around the middle position the epicycloid pendulum tracks corresponding to a given pendulum order are retained, at large oscillation angles the pendulum order is lowered by lowering the curvature of the pendulum tracks in relation to the epicycloidal pendulum tracks at the transition. Although this reduces the degree of isolation, however, the insulation completely disturbing attacks are avoided and thus avoided noise and avoided the vibration damper stressful or damaging attacks the absorber masses on the disk part.
